Harries has optioned the life story of Alan Renshaw, the music teacher at a London public school who was eventually canned after he got his students the gig in Roger Waters' rock opera.

There is, however, a major stumbling block: Harries doesn't yet have the rights to the song at the center of the film. Whether or not Waters harbors any resentment toward the kids in the choir over their 2004 demands for royalties remains to be seen.
